With the 2012 Presidential election only days away, we’re reaching the culmination of a long and hard-fought campaign—one that has been distinctly 21st century, thanks to the ever-increasing role of technology. Consider just a few of the ways that it is altering the political process: SMS is being used to reach voters and seek contributions; online data is being put to work to target ads; and Twitter has seen incredible traffic during the recent Presidential and Vice Presidential debates. How strange then that the actual process of voting is still rooted in analog technologies of the past.

Voter participation in U.S. Presidential elections has changed dramatically over time. Interestingly, it peaked in 1876, when nearly 82 percent of eligible voters cast ballots. (Of course voter eligibility in the 19th century was very different than it is today.) As the chart below illustrates, over the past hundred years the percentage of eligible voters who have cast ballots has dropped precipitously since 1876, and typically hovers between 50 to 60 percent. How then might voting be made easier, more accessible, more efficient and more secure?

This answer may seem counterintuitive, but it’s time to take voting out of the booth and move it to the computer, smartphone or tablet—bringing digital devices and democracy together just makes sense. According to research from The Pew Internet and American Life Project, ownership of digital devices among adults is high and will almost certainly continue to grow.

Device ownership is especially high among young people, who also happen to be the segment that is least likely to vote. Supplementing the voting booth with the types of digital devices so many Americans already rely on and are comfortably using could truly democratize the electoral process by allowing voters to cast their ballots whenever and wherever is convenient for them. (This is already the case for early and absentee voting with paper ballots here in the United States and online voting is being explored in several countries.) Without suggesting a causal relationship, if the ballot were to become accessible via, say, an app or even SMS , it would only be logical to expect voter participation levels to rise.

Obviously there are questions about implementation—some technical and some procedural—that need to be considered. Here are four big picture challenges, as well thoughts on possible ways to address them:

Voter Eligibility Voters would need to state their intention to vote via a device and register that device with election officials prior to using it to cast their ballot. As with early or absentee ballots, digital ballots would need to be cast within a specified time frame. Voters would also need to receive email or SMS confirmation that their vote has been received, in the event questions were to arise later.

Voter Verification Strong authentication would be needed to ensure each voter cast only one ballot. This could be accomplished with biometric security, two-factor authentication or device recognition/registration.

Device Verification There would also need to be a way to ensure a single device wasn’t responsible for an inordinate number of votes. Device recognition coupled with user verification or a device registry could limit the potential for this occurring.

Voter Privacy While ensuring an individual is casting only one vote and that a single device isn’t casting multiple votes, a very real and important concern is maintaining the secrecy of every voter’s ballot. One can imagine solutions (such as creating dual anonymized hashes, one for the voter and the other for the device, or encrypting voter information once the ballot is entered, etc.) that would allow a vote to be cast without tying it to a specific individual.

None of these issues are insuperable. On the contrary, with current technology and ingenuity they could be addressed and make digital voting a practical alternative. Which is also to say that for the near future it wouldn’t become a substitute for all current analog voting systems, as there will always be people that need or want the experience of going to their local polling station and casting their vote in person. Providing a simple, secure and readily available digital alternative however just makes sense in this day and age.
